Abstract

The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of radioactive iodine. During the first two years of this program we have examined the potential of Fullerene Containing Carbon compounds (FCC) developed by KRI, and natural organic matter (NOM) as sorbents for iodine released during the reprocessing of nuclear fuel. This work involved the development of bench-scale testing of the FCC and NOM material in a simulated process off-gas environment.

Research Objectives and Goals

• Develop bench-scale experimental set-up and procedures for simulating PUREX head-end vapor phase; Develop experimental procedures for evaluating I sequestering methods using bench scale procedures.

• Develop FCC-bearing material as potential I sequestration matrix.

• Determine binding of iodine to FCC and NOM.

• Examine alternate I sequestration matrices using techniques developed for FCC and NOM studies.

• Examine the effect of reaction conditions on binding.

• Elucidate the nature of the reaction products (volatile, hydrophobic, soluble, insoluble). See Figure 1 for example.

• Develop methodology and host matrix for converting sequestered I to solid matrix for evaluation as transmutation target and/or disposal matrix.

• Examine recovery of I from sequestration matrices using combustion, hydrolysis and pyrolysis methods.
